The innovative approach of the present invention is mainly reflected in, by the precise electronic shutter of adjustable switch time to excitation source
Chopping the light is carried out, the dynamic behavior and characteristic of optoelectronic pole near surface bubble, including bounce-back, collision wall, sliding, merging is controlled
The behavior such as diminish with bubble departure diameter, so that effectively influence of the control bubbling behaviour to the heat and mass efficiency of system.
The present invention is based on said apparatus and method, provides following examples：
Embodiment 1：The bounce-back behavior of electrode surface bubble
The present embodiment will describe the method for obtaining bubble bounce-back behavior, and the behavior is described in more detail, and have
Body is implemented as follows：
Embodiment condition：Electrolyte is 0.5mol/L Na2SO4Solution, laser power 13mW is biased 0V, sets fast
Door opening time is 0.1s, and the shut-in time is 0.05s.
Embodiment result：Fig. 3 is that above-mentioned implementation condition bubble position changes over time curve map with radius size, is sat
Mark (x, y) represents bubble phase to location of growing point, and x directions are perpendicular to wall, and y is oriented parallel to vertical dotted line in wall, figure
Represent the shutter release moment.From curve, bubble experienced six times before eventually disengaging from and depart from and five bounce-backs, right below
Bubble bounce-back behavior is described in detail：
1. shutter open, bubble electrode surface laser shot centre nucleating growth, or irradiation immediate vicinity
Irradiation central growth is slid onto after nucleation, bubble radius become big with irradiation time, and centre of sphere x coordinate becomes big, and y-coordinate position is relative
Keep constant, this stage bubble is attached to wall growth；
2. during shutter close, bubble departs from surface and stopped growing immediately, i.e., radius size is not changed over time, bubble position
Put and become big x, y direction are relative, y directions at the uniform velocity, the variable motion of x directions；
3. shutter is again turned on, bubble reaches maximum and starts counter motion in x directions distance, and y directions are continued at the uniform velocity
Rise, Air Bubble Size keeps constant, and after shutter opens a period of time, bubble at the uniform velocity rises to extreme higher position, lower a moment bubble
Electrode surface, i.e. x, y-coordinate is rapidly returned back to diminish rapidly, collision electrode surface after bubble-slip to irradiation position continued growth,
Into cyclic process next time；
It is uniform motion in vertical direction 4. bubble departs from rising every time, with the increase of bubble diameter, bubble rises
Speed increase, and the time on disengaging surface is increasing after bounce-back every time, therefore the distance risen is increasing, eventually disengages from electrode
Surface.
As can be known from the above analysis, bubble also can collide and slide on wall while occurring bounce-back behavior
Behavior, if suitably changing operating mode, can also obtain the merging behavior of bubble, and because the opening time of shutter is sufficiently small,
The detachment frequency when detachment frequency of bubble is than without chopping the light is small, and these behaviors will be provided in the embodiment below.
Embodiment 2：Shutter release time effects bubble bounce-back rule
Above embodiment gives the method for obtaining bubble bounce-back behavior and bounce-back behavior is described in detail,
The present embodiment will obtain corresponding bubble bounce-back rule by setting the different shutter release time, be embodied as follows：
Embodiment condition：Electrolyte is 0.5mol/L Na2SO4Solution, laser power 13mW, is biased 0V.When probing into
When shutter opening time is to air bubble growth cycle and the influence of bounce-back number of times, the setting shut-in time is 0.05s, is closed when probing into shutter
When closing influence of the time to air bubble growth cycle and bounce-back number of times, setting opening time is 0.075s.
Embodiment result：Fig. 4 gives the influence for the shutter release time number of times and growth cycle averagely being rebounded to bubble.It hurry up
The timing of door shut-in time one, with the increase of opening time, bounce-back number of times reduces, growth cycle increase, when open between be more than
Rebound phenomena disappears during 1s, and growth cycle is equal to opening time, and opening time is more than 26s (normal lifes of bubble when without chopping the light
Long period) when, the air bubble growth cycle keeps 26s constant；The timing of shutter opening time one, with the increase of shutter closing time,
Bubble averagely rebounds number of times and growth cycle reduces, upon closing between when being more than 0.2s rebound phenomena disappear, bubble is averagely given birth to
Long period is approximately equal to shutter opening time.
Embodiment 3：Chopping the light controls bubble to occur sliding with merging behavior in wall
The sliding of bubble occurs during the once bounce-back of bubble with merging in the present embodiment, is embodied as follows：
Embodiment condition：Electrolyte is 0.5mol/L Na2SO4Solution, laser power 13mW is biased 0V, sets fast
Door opening time is 0.075s, and the shut-in time is 0.2s.
Embodiment result：The shutter release time provided in the present embodiment can control bubble to occur sliding in wall and close
And, as shown in Figure 5.Bounce-back occurs after shutter opening for the bubble of top and in wall slippage in figure, while in irradiation position production
A raw new bubble is simultaneously grown up, and after bubble-slip to the growing point of bounce-back, new bubble first is forced down into a segment distance subsequent
Generation merges deformation, and the bubble after finally merging departs from wall and risen, and this bubble is led after merging because center of gravity changes
The disengaging of cause is different from occurring disengaging reason in embodiment 2 because of shutter close.
Embodiment 4：Chopping the light makes bubble departure diameter diminish
When being less than the growth time of bubble during without chopping the light between when the shutter is opened, bubble can be prematurely popped out, therefore depart from straight
Footpath and growth time can all reduce, and be given in the present embodiment in the case of bubble do not rebound, shadow of the chopping the light to detachment frequency
Rule is rung, is embodied as follows：
Embodiment condition：Electrolyte is 0.5mol/L Na2SO4Solution, laser power 1-19mW, is applied
Biasing 0.02-0.18V, shutter opening time is 2s, and the shut-in time is 0.15s.
Embodiment result：Because the shutter release time is sufficiently large in the present embodiment, bubble departs from immediately after shutter close
Wall, bubble does not rebound, therefore shutter opening time is the growth time of bubble.In different laser power and bias
Under, the ratio of bubble departure diameter is different when the detachment frequency of bubble is from without chopping the light, and the ratio that table 1 is given under different operating modes is big
It is small.
The ratio between bubble departure diameter under the different operating modes of table 1
From table 1 it follows that under different permanent biass, laser power is bigger, and the ratio of bubble departure diameter is smaller, that is, cuts
Influence of the light to detachment frequency is bigger.Such as laser power be 1mW when, detachment frequency be without the 80%-95% under the conditions of chopping the light,
And when laser power is 19mW, detachment frequency is only without 40% or so under the conditions of chopping the light, as a result as shown in Figure 6.
It should be noted that the part example that the apparatus and method that embodiment described above is based only on the present invention can be realized
Son, the invention is not restricted to these embodiments, those of ordinary skill in the art are by reading description of the invention to skill of the present invention
Any equivalent conversion that art scheme is taken, is that claim of the invention is covered.
